Hi, Malene! As an Engish teacher myself in local high school here in the Philippines, I am thrilled to turn in my proposal for your project. I have six years of experience in language and literature education working with high schoolers who for the most part need help to develop love for reading. Working to help you get the word out about your amazing work will be such a joy. Like you, I love stories too.
Here's what I plan on doing.
Sticking to your brand will be crucial. So I'll have to take a thorough look at your book, its theme, core message, characters, and design. It is important that the marketing materials that we put out there reflect exactly that. It is also of great value that your Instagram page although meant to put in commercial work, will remain personal and solemnly attached to the motivation that led you to its writing.
You mentioned in a video posted on your website that this books kind of serves like a love letter to young girls (and the older ones' inner child). An Instagram page has very slim chance of reaching them firsthand for obvious reason. So I propose to make the materials connect to those that surround these young girls and who give them the support they need as they make sense of the world as young girls - the teachers, the mothers, guardians, parents, etc.
Finally, I'd be very willing to listen to your inputs as well. After all, you birthed this worthwhile project out of your soul and heart.
I look forward to hearing from you. Thanks!
